HD 169142 0.9 mm continuum emission (grey-scale) with coloured contours showing the 60, 70, 80, and 90% integrated flux values for C34S and SO in the left panel and HC3N and CH3OH in the right panel. The green dot gives the location of the giant planet at 37 au (Gratton et al. 2019; Garg et al. 2022; Hammond et al. 2023). The different beams for each molecular line are shown in the same colours as the contours.
